To allwhom it may concern: slightly so as to provide a somewhat conicalBe kn wn t t. I L LEI, a citizen of the United 'States residat Newark inthe county of Essex and State of New erse have invented certain em anduseful improvements in Gas- .u nes otwhich he. iq o ng s a full, dam andexact sp ifica ion lim t .1 relates to gas burners, and for its, ob'ectsto, provide'a thermostaticactuat gas. burner wherein t e gas. beautomatica turned off and on. by the and t es of he at and whelfs he gasv v w l e p 16 ated by a In t wlthout involving mechanical connectionsbetween the therm combination with a steel ball or oiiller magnetievalve disposed the gas pillar a movable exter or magnet which is movedtoward and from the valve by the contracion and expansion of athermostat which is d to. beheated by the (gas flame, the gas. flamebeing itself controlleby the openor do of; the magnetic valve.

the pr erred embodiment of the inven tien diselosed a spring normallytends to, move the magnet away from the valve .30 thereby the valve toclose by gravity, which tendenc of the spring 1s resi te by the on 0 ththe mo t d the. spring is rendered efiective to move the magnet away andthereby to permit the valve 3 o c use when the tension of'the thermostatis relieved by the heating efiect of the flame. In he ass mrany drawinFigure 1 rep esents. n pe sp i e g urner bodying the invention; F g. 2is a view seen from the left side of 1 in section, showing the mountingof thethermostat and the tension adjusting means; and Fig. 3 is a viewshowi g 8 modified form.

1 re resents a gas pillar having a base 2 4.5 and'a apted to be screweden te a gas supply pipein the well known manner.- .3 is a, hume'r tubeadapted to be connected to the gas illar 1 and'carrying the tip 4. P er1 is pre i s w a s. p s sageie med in a p ug magnet cm a e upper and owinch plug be l v. Km l shaped seat 6 on which a steel ball 7- ispermitted to move. The steel or other magnetic ball normally rests bygravityover the end of the passage in plug 5 which is so arranged that aslight leakage of gas can take place around the'ball 7 suflicient'to keethe flame at the tip always lighted. The p ug 5 is magnetized, so thatthe ball seats quickly without oscillation. At the upper end of the tube3 a block 8 is provided with lugs 9,.9 to which is rigidly attached abow tube 10. The tube 10 may be of closely coiled wire or a continuoustube having sutficient rigidity to withstand the tension of athermostatic wire 11,.preferably of brass. The wire 11 is attached atits lower end to an eye 12 which screws into a socket 13 carried onthe-base tube for adjustin the tension of the wire 11. The other end 0%the wire passes through the tube 10 and is attached at 14 to one end ofa lever 15 pivoted on the block 8 at 16. Attached to the longer end ofthe lever 15 by a plate 17 and a screw 18 is a horseshoe magnet 19 havinits poles disposed opposite the ball 7, whic acts as the ma et armature.When the wire 11 is cooled, it is normally under tension sufiicient tohold the magnet against the resistance of a spring 20 against theoutside-of the gas illar 1, thereby attracting the steel ba 7 away fromthe seat and permitting the maximum quantity of gas to flow, candlepower to the flame. static wire 11 heats up, its tension relaxes and thespring 20 is thereby enabled to throw the magnet outward so that theball 7-is no longer attracted. The ball 7 therefore drops y gravity onits seat cutting down the flame to a very small extent; thereupon, thewire 11 contracts and pulls the magnet inward again permitting the ballto be attracted from its ving full As t e thermo seat and causing theflame toenlarge. This o eration'continues automaticall as lon as te'burner is kept lighted, and as be ore stated, it is provided that whenthe ball is on the seat suflieient as shall leak around it to keelp averysmall ame at the tip. 7

In ig. 3, the thermostat 23 comprises a be mp nd meta r p sp e 1 3iniity to the flame which when eate will cause a lug 24 on the lower endto move inwardly so as to engage a lug 25 on the lever 26, and therebymove the magnet away from the ball permitting it to drop back on theseat and cut down the flow of gas. When the flow is cut down thethermostat expands outwardly permitting the magnet to again drop back'and pull the ball off the seat.

From the foregoing description it will be seen that an automatic gasflashing device is provided wherein the use of mechanical connectionsbetween the thermostat and the valve is obviated, and wherein the gasvalve is opened by magnetic attraction and closed by gravity. Bymagnetizing the ball seat, the valve closes uickly preventing flickeringof the flame. 'l 'ereby, the device is more effective for advertisingpurposes. Also it will be seen that in the form shown in Figs.

11' and 2, the magnet is operated positively in one'direction by aspring and 1n the otherdirection by the tension of a thermostatic' wire.By varyin the tension of the wire it will be seen that t e time of theflashes can be controlled. In Figs. 1 and 2 the tube 10 may be made ofsuch size and shape as to.

practically surround the flame, or it maybe disposed in the flame ifdesired. By this construction, it is wire when heated and cooled andthereby control the amount of movement to be given the magnet actuatinglever 15.
